Re: Difference between Prereq: and Requires:

["Diane Reichlen" <dreichlen symantec com>]

So *if* a packageA has a "provides:" equal to what packageB has as a
"Prereq:" then pkgorder will (assuming all else is okay) order packageB
after packageA.  But what of packages that don't have "provides:"?  How can
I force my package to be the last package installed?

There is no difference between PreReq: and Requires:, *except*

             PreReq: is a hint used for package ordering, and a package
             which contains the matching provide is guaranteed to be
             installed before whatever package has the PreReq:.

Even that PreReq: distinction is moot these days *except* when a dependency
loop is encountered, in which case the loop will be trimmed on Requires:,
leaving PreReq:'s as is.
